72W UV/LED Lamp? It Might Only Be 72W on Paper! How to Check the Real Power

In recent years, more and more UV/LED nail lamps have been advertised with extremely high power ratings – 72W, 80W, or even 120W. But are these numbers real? Based on professional experience, there are very few UV/LED lamps on the market that truly exceed 48 watts. Despite this, many manufacturers display much higher wattage figures on the packaging for marketing purposes. In this article, we show you how to easily check the real power.

What does watt (W) really mean?

Watt is the unit of power. In the case of a UV/LED lamp, it determines:

how strongly the gel cures
how fast the polymerization is
how stable the curing process is

The more accurate the stated power, the more predictable your work will be.

How to check the real power?

The trick is very simple.

Check the side of the lamp box or the label on the adapter, where two important values are listed:

Volts (V)
Amps (A)

To calculate the real maximum power:

Volts × Amps = Watts

Example:

If the adapter shows: 24V and 2A
Calculation: 24 × 2 = 48W

This means the lamp’s maximum power output is 48 watts.

What happens with many “72W” lamps?

In many cases, the front of the box states 72W, but if you check the adapter label, you may see something like:

24V × 1.5A
Calculation: 24 × 1.5 = 36W

This is significantly lower than the advertised 72 watts.

This does not necessarily mean the lamp is unusable – but there can be a large difference between the marketing number and the real performance.

Why is this important for nail technicians?

A lamp with lower real power:

may not cure builder gel properly
can cause issues when working with polygel
does not ensure even curing
may reduce durability
can lead to customer dissatisfaction

Professional work requires reliable tools.

How to buy a UV/LED lamp consciously?

Before purchasing, always:

✔ Check the Volts and Amps values on the adapter
✔ Multiply the two numbers
✔ Verify whether the result matches the advertised wattage
✔ Do not rely only on the marketing number shown on the box

This simple check can protect you from misleading information.

Summary

Currently, there are very few UV/LED lamps on the market that truly exceed 48 watts. If a lamp is advertised as 72W, it is worth checking the adapter label and calculating the real power:

Volts × Amps = Real Watts

Conscious purchasing leads to better work, more stable curing, and more satisfied clients in the long run, and Diamond Nails helps you achieve that.
